The default for the capacitors sort is ceramic, preferably the npo 1% sort or equivalent. But essentially nothing crucial here. Use any capacitor you’ve got laying arround, but no electrolytic or tantalum caps. Do not go out and rush to the store. Most parts may be salvaged from somewhere. Only in the event you intend to make use of this circuit outside the home you may need to choose much more temperature stable capacitors.
